Deep Mapping of Small Solar System Bodies with Galactic Cosmic Ray Secondary Particle Showers

Completed Technology Project

Project Introduction

We will investigate the use of galactic cosmic ray (GCR) secondary particles to probe the deep interiors of small solar system bodies (SSBs), including comets, asteroids, and geologic structures on the surfaces of airless bodies.

We propose to develop new types of spacecraft instrumentation, data analysis, and imaging methods that make use of galactic cosmic ray (GCR) secondary particle shower products, such as pions and muons.
